Milli Hill is a journalist, author and the founder of the Positive Birth Movement. Her first book, The Positive Birth Book, was published in March 2017 to wide acclaim, immediately becoming an Amazon bestseller and remaining one of the most popular books for pregnant women ever since. In August 2020 her second book, Give Birth Like a Feminist, was published by Harper Collins and has since been widely featured in the UK media including the BBC. The book seeks to spark debate about childbirth as an overlooked feminist issue, and urges women to reclaim their bodily autonomy in birth in line with the #metoo movement. In 2021 her book My Period, a puberty guide for preteen girls was published by Wren and Rook (Hachette). In 2025 her 4th book Ultra Processed Women was published by Harper Collins. Milli speaks regularly at international events and conferences and has appeared on BBC Radio 4, BBC Radio 2, BBC 5 Live and talkradio. She has written extensively for the Telegraph, Guardian, Independent, ipaper and more about issues connected to motherhood, birth, and women's rights and autonomy. She now writes a bestselling substack WHAT ABOUT WOMEN, and is launching another substack, Unprocess, about how diet is key to health. Milli lives in rural Somerset with her partner and three children. Her 5th non fiction will be published in 2026.
